Description

Technical Field

[0001] This invention relates to the field of busbar processing technology, and in particular to a precision machining equipment for busbar through-hole burrs based on automatic alignment processing. Background Technology

[0002] Busbars, as the core material of high and low voltage switchgear busbars, are primarily connected by bolts in most applications. However, this connection method requires drilling holes in the busbar lap surfaces. Inevitably, burrs will be generated around the bottom of the through-holes during the drilling process. If these burrs are not thoroughly removed, they can cause a series of problems during the operation of the high and low voltage switchgear, such as increased busbar return resistance, abnormal temperature rise, and oxidation reactions at adjacent contact interfaces. Ultimately, this could lead to safety accidents and pose a serious threat to the safe operation of the high and low voltage switchgear.

[0003] For example, the automatic alignment busbar through-hole deburring device disclosed in CN210937484U, through multiple protrusions on the mold corresponding to the positions of the busbar through holes, combined with the mold lifting movement and the sliding groove on the mold base for placing the busbar, can achieve synchronous deburring of multiple through holes and improve processing efficiency. However, it still has the following limitations in use:

[0004] (1) When removing burrs around the bottom of the busbar through hole, if the burr side of the busbar through hole is located at the bottom, the protrusion will still push the inner wall burrs to the lower surface of the busbar during the extrusion and cutting process, and the burrs cannot be removed. Therefore, in order to achieve the ideal cutting effect, it is necessary to distinguish the front and back sides of the busbar.

[0005] (2) Regarding the problem of partial hole position deviation after machining multiple through holes on the busbar, the equipment uses a protrusion in a fixed position for extrusion cutting, lacking an automatic hole position deviation compensation function. This results in the inability to fully and effectively remove the burrs of the through holes with hole position deviation when processing multiple through holes simultaneously. Furthermore, the mismatch between the protrusion and the hole position causes the hole position to expand, affecting the high-quality machining of the busbar.

[0006] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic alignment and deburring finishing device for busbar through holes to solve the aforementioned technical defects. This invention first uses a dual-station positioning component to achieve adaptive positioning and clamping of busbars of different thicknesses to improve its applicability. Then, combined with upper and lower cutting components, it eliminates the need to distinguish between the front and back of the busbar and achieves efficient deburring through cutting and extrusion. In addition, it can compensate for the hole position deviation of some through holes on the upper part of the busbar, avoiding the problem that when multiple through holes are processed simultaneously, the burrs of the corresponding through holes cannot be completely removed due to partial hole position deviation, which can cause hole enlargement.

[0008] The objective of this invention can be achieved through the following technical solution: an automatic alignment and processing device for burr finishing of busbar through holes, comprising a fixed base plate, an upper frame and a lower frame disposed on one side of the fixed base plate, a dual-station positioning component disposed on the fixed base plate and located between the upper frame and the lower frame, and upper and lower frames respectively disposed on the upper frame and the lower frame.

[0009] The dual-station positioning component performs adaptive centering clamping and positioning processing for busbars of different sizes. The upper cutting component performs extrusion cutting burrs on the busbar through holes to autonomously float and compensate for hole position deviations. The lower cutting component works with the upper cutting component to perform cutting burr removal on the busbar through holes to follow and compensate for hole position deviations.

[0010] Preferably, two sets of L-shaped plates distributed vertically are slidably connected on the fixed base plate, and a first servo motor is installed by bolts.

[0011] Preferably, the upper frame is fixedly connected to the upper L-shaped plate, the lower frame is fixedly connected to the lower L-shaped plate by a first spring, and a guide rod that slides with the lower L-shaped plate is fixedly connected to the lower frame.

[0012] Preferably, the dual-station positioning assembly includes an electric cylinder slide fixedly mounted on a fixed base plate, and a fixed frame is fixedly mounted on the slide of the electric cylinder slide. Positioning cavities are symmetrically opened on both sides of the fixed frame, and a limit plate and two sets of V-shaped clamps are provided in the positioning cavities.

[0013] Preferably, the fixed frame is rotatably connected to a bidirectional lead screw that is threadedly connected to two sets of limiting plates, and the limiting plates are slidably connected to the positioning cavity. A rotating wheel is fixedly connected to the bidirectional lead screw. An electric push rod that drives the corresponding V-shaped clamp to move is installed on the fixed frame by bolts. A guide rod that slides with the fixed frame is fixedly connected to the V-shaped clamp.

[0014] Preferably, both the upper and lower frames are fitted with fixing plates by bolts. The upper cutting assembly includes a threaded mounting post. An upper mounting seat is fitted with a bolt on the fixing plate of the upper frame. A tapered guide post is fixedly connected to the bottom of the threaded mounting post, and the radial section of the tapered guide post has a toothed structure. A saw blade and a flat blade are sequentially fixed to the threaded mounting post and above the tapered guide post.

[0015] Preferably, the upper mounting base has an upper movable frame slidably connected inside, and the upper movable frame has an upper movable block slidably connected inside, which is threadedly connected to the threaded mounting post. Four sets of second springs arranged in a cross shape are fixedly connected between the upper movable block and the upper movable frame, and between the upper movable frame and the upper mounting base.

[0016] Preferably, the lower cutting assembly includes a threaded mounting tube, a lower mounting seat is bolted to the fixing plate of the lower frame, a flat-mouth cutter is fixed to the top of the outer wall of the threaded mounting tube, and a saw cutter is fixed to the inner U-shaped block, and a chip cylinder is threaded to the bottom of the threaded mounting tube.

[0017] Preferably, the lower mounting base has a lower moving frame slidably connected inside, and the lower moving frame has a lower moving block slidably connected inside, which is threadedly connected to the threaded mounting pipe. Both the lower mounting base and the lower moving frame are rotatably connected to screws, and a second servo motor that drives the corresponding screws to rotate is fixedly installed. The lower moving frame and the lower mounting base are threadedly connected to the corresponding screws.

[0018] Preferably, a photoelectric sensor transmitter is mounted on the U-shaped block, a photoelectric sensor receiver is mounted at the bottom of the conical guide post, and a control panel is mounted on the fixed base plate.

[0019] The beneficial effects of this invention are as follows:

[0020] (1) The present invention, through the two sets of V-shaped clamps and limiting plates in the dual-station positioning component, can not only perform adaptive positioning and clamping processing of busbars of different thicknesses to improve the applicability, but also simultaneously replace the busbars during the extrusion cutting process, further improving the overall burr processing efficiency; through the upper cutting component and the lower cutting component, the busbar through hole can achieve scissor extrusion burr removal processing, without distinguishing between the front and back of the busbar, and can effectively remove burrs that are tilted to one side in the busbar through hole, further improving the convenience of processing;

[0021] Furthermore, by combining the rigid downward movement of the upper frame with the elastic upward movement of the lower frame, the tangential cutting process automatically converts into a single downward cutting process after the tangential cutting, thereby achieving the finishing treatment of the inner wall of the through hole between the threaded mounting column and the threaded mounting tube, ensuring a comprehensive treatment effect.

[0022] (2) The present invention uses the universal movable installation of the bolt mounting column and the tapered guide column at its bottom to automatically correct the position of the threaded mounting column when there is a centerline deviation between the busbar through hole and the tapered guide column. The tapered guide column contacts the side wall of the busbar through hole through the inclined surface of the tapered guide column. In addition, the transmitter and receiver of the photoelectric sensor work with the control panel to make the threaded mounting tube move horizontally in sync with the bolt mounting column. This automatically compensates for the deviation of the busbar through hole position, so as to avoid the problem that the burrs in the through hole cannot be completely removed and the hole position is enlarged due to the partial hole position deviation of the busbar through hole during the extrusion cutting burr process.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figures 1-6 , Figure 9 and Figure 12 As shown, the existing technology requires distinguishing between the front and back of the busbar for placement, and it is difficult to adapt to different sizes of busbars, requiring the replacement of the matching mold base, which increases the inconvenience of use. The following solution can be used to solve this problem:

[0043] In this embodiment, the automatic alignment processing busbar through hole burr finishing equipment includes a fixed base plate 1, an upper frame 11 and a lower frame 12 disposed on one side of the fixed base plate 1. Through the relative movement of the upper frame 11 and the lower frame 12, the corresponding upper cutting component 3 and lower cutting component 4 are driven to perform slitting burr removal. A dual-station positioning component 2 is disposed on the fixed base plate 1 and between the upper frame 11 and the lower frame 12. The upper frame 11 and the lower frame 12 are respectively provided with corresponding upper cutting component 3 and lower cutting component 4.

[0044] The dual-station positioning component 2 performs adaptive centering clamping and positioning of busbars of different sizes. The upper cutting component 3 performs extrusion cutting of burrs on the busbar through holes by autonomous floating to compensate for hole position deviation. The lower cutting component 4 works with the upper cutting component 3 to perform cutting removal of burrs on the busbar through holes by following and compensating for hole position deviation. Through the cooperation of the upper cutting component 3 and the lower cutting component 4, the busbar through holes are subjected to cutting and extrusion cutting and removal of burrs. There is no need to distinguish between the front and back of the busbar. It can effectively remove burrs that are tilted to one side in the busbar through holes, thereby improving the convenience of processing.

[0045] Two sets of L-shaped plates 13, arranged vertically, are slidably connected to the fixed base plate 1. A first servo motor 14 is mounted on the base plate 1 by bolts. A gear 15 is mounted on the output shaft of the first servo motor 14. A toothed plate 16 that meshes with the gear 15 is fixedly connected to the L-shaped plate 13. The first servo motor 14 drives the gear 15 to rotate. By combining the meshing of the two sets of toothed plates 16 with the gear 15, the upper frame 11 and the lower frame 12 can move synchronously relative to each other.

[0046] The upper frame 11 is fixedly connected to the upper L-shaped plate 13 to achieve rigid descent of the upper frame 11. The lower frame 12 is fixedly connected to the lower L-shaped plate 13 with a first spring 17 to achieve elastic descent of the lower frame 12. A guide rod is fixedly connected to the lower frame 12 and slides with the lower L-shaped plate 13 to limit the lower frame 12 to only perform lifting and lowering movements.

[0047] The dual-station positioning assembly 2 includes an electric cylinder slide 21 fixedly mounted on a fixed base plate 1. The electric cylinder slide 21 is used to switch between two sets of positioning cavities to achieve the effect of alternately fixing the busbar. This allows the busbar to be replaced synchronously during the extrusion and cutting process, further improving the overall burr processing efficiency. A fixing frame 22 is fixedly mounted on the slide of the electric cylinder slide 21. Positioning cavities are symmetrically opened on both sides of the fixing frame 22. A limit plate 23 and two sets of V-shaped clamps 24 are provided in the positioning cavities.

[0048] The busbar is placed between two sets of V-shaped clamps 24 in one side positioning cavity, and one side abuts against the corresponding limiting plate 23. The limiting plate 23 restricts the length of the busbar inserted between the two sets of V-shaped clamps 24 and the relative movement of the two sets of V-shaped clamps 24. Combined with the V-shaped groove of the V-shaped clamp 24, the busbar of different thicknesses is subjected to adaptive positioning and clamping treatment with vertical centering, so as to achieve the stability effect in the busbar processing process and the alignment effect of the busbar through hole with the upper cutting component 3 and the lower cutting component 4.

[0049] A bidirectional lead screw 25 is rotatably connected to the fixed frame 22 and threadedly connected to two sets of limiting plates 23. The limiting plates 23 are slidably connected to the positioning cavity. A rotating wheel is fixedly connected to the bidirectional lead screw 25. By rotating the rotating wheel, the bidirectional lead screw 25 is rotated, and the positions of the two sets of limiting plates 23 in the positioning cavity are adjusted synchronously, thereby further positioning the busbar through hole in the radial direction. An electric push rod 26 is bolted to the fixed frame 22 to drive the corresponding V-shaped clamp 24 to move. The corresponding electric push rod 26 pushes the V-shaped clamp 24 to move relative to each other. A guide rod 22 is fixedly connected to the V-shaped clamp 24 and slides with the fixed frame 22 to realize the horizontal and stable movement of the V-shaped clamp 24.

[0050] Both the upper frame 11 and the lower frame 12 are bolted with fixing plates 18. The fixing plates 18 are provided with elongated holes for the corresponding bolts to pass through, so as to realize the position of the fixing plates 18 themselves, as well as the connection position adjustment of the upper mounting base 32 and the lower mounting base 42, thereby realizing the installation of the threaded mounting column 31 and the threaded mounting tube 41 and the corresponding female busbar through hole at the corresponding positions.

[0051] The upper cutting component 3 includes a threaded mounting post 31, and an upper mounting base 32 is bolted to the fixing plate 18 of the upper frame 11. A tapered guide post 33 is fixedly connected to the bottom of the threaded mounting post 31, and the radial section of the tapered guide post 33 has a toothed structure. A saw blade 34 and a flat blade 35 are sequentially fixed to the threaded mounting post 31 and above the tapered guide post 33.

[0052] The saw blade 34 on the threaded mounting post 31 has multiple through openings for the downward discharge of burr debris cut by the flat blade 35. By combining the saw blade 34 with the flat blade 35, large burrs are first quickly torn apart, and then the surface is smoothed, achieving high-efficiency burr removal.

[0053] The lower cutting assembly 4 includes a threaded mounting tube 41, a lower mounting base 42 is bolted to the fixing plate 18 of the lower frame 12, a flat-mouth cutter 35 is fixed to the top of the outer wall of the threaded mounting tube 41, and a saw cutter 34 is fixed to the inner U-shaped block 43. The bottom of the threaded mounting tube 41 is threaded to a chip cylinder 44. Through the relative movement of the upper frame 11 and the lower frame 12, the corresponding threaded mounting post 31 and the threaded mounting tube 41 are driven into the mother bar through hole.

[0054] The large burrs inside the through hole are cut by the saw cutter 34 on the threaded mounting post 31 and the threaded mounting tube 41. Then, the inner wall surface of the busbar through hole is quickly trimmed by the flat cutter 35. The cut burrs are guided into the threaded mounting tube 41 by the saw cutter 34 and the flat cutter 35 on the threaded mounting tube 41, and then collected in the chip cylinder 44. Through the relative movement of the threaded mounting post 31 and the threaded mounting tube 41, the burrs in the busbar through hole are cut by deep and rapid extrusion, thus avoiding the need to distinguish the front and back of the busbar before placement.

[0055] Subsequently, as the threaded mounting post 31 continues to move downwards, and the tapered guide post 33 comes into contact with the U-shaped block 43, the rigidity of the upper frame 11 decreases and the elasticity of the lower frame 12 increases, pushing the threaded mounting tube 41 to move downwards relative to each other, compressing the first spring 17, and the saw cutter 34 and flat cutter 35 on the threaded mounting post 31 perform a comprehensive finishing process on the inner wall of the through hole between the threaded mounting post 31 and the threaded mounting tube 41.

[0056] Example 2: Please refer to Figures 6-12 As shown, the lack of automatic hole position deviation compensation function, which leads to the inability to fully and effectively remove burrs from through holes with position deviations during simultaneous processing of multiple through holes, and causes hole enlargement, can be solved by the following solution:

[0057] In this embodiment, both the upper frame 11 and the lower frame 12 are bolted with fixing plates 18. The upper cutting component 3 includes a threaded mounting post 31. An upper mounting seat 32 is bolted to the fixing plate 18 located on the upper frame 11. A tapered guide post 33 is fixedly connected to the bottom of the threaded mounting post 31. During the synchronous relative movement of the upper frame 11 and the lower frame 12, the tapered guide post 33 at the bottom of the threaded mounting post 31 first contacts the busbar through hole. If there is a centerline deviation between the busbar through hole and the tapered guide post 33, the inclined surface at the bottom of the tapered guide post 33 causes the threaded mounting post 31 to move horizontally and autonomously correct the position of the threaded mounting post 31.

[0058] This causes the axis of the threaded mounting post 31 to coincide with the center line of the corresponding mother row through hole, achieving the effect of extrusion cutting burrs by autonomous floating to compensate for hole position deviation. The radial section of the tapered guide post 33 has a toothed structure, which is used to allow the burr debris cut by the saw cutter 34 and flat cutter 35 on the threaded mounting post 31 to fall into the threaded mounting tube 41 below. The saw cutter 34 and flat cutter 35 are fixedly connected to the threaded mounting post 31 and above the tapered guide post 33 in sequence.

[0059] The upper mounting base 32 has an upper moving frame 36 that is slidably connected inside, and the upper moving frame 36 has an upper moving block 37 that is threadedly connected to the threaded mounting post 31. The threaded connection between the threaded mounting post 31 and the upper moving block 37 is used to replace the corresponding cutter, thereby adapting to the extrusion cutting of burrs in various shapes of busbar through holes. A limit hole is opened on one side of the outer wall of the threaded mounting post 31. An ear plate is fixedly connected to the top of the upper moving block 37, and a limit screw that is threaded on the ear plate and inserted into the corresponding limit hole is used to realize the anti-deviation limit after the threaded mounting post 31 is connected, so as to ensure the accurate processing of irregular busbar through holes.

[0060] Four sets of second springs 38 arranged in a cross shape are fixedly connected between the upper moving block 37 and the upper moving frame 36, and between the upper moving frame 36 and the upper mounting base 32. The sliding installation of the upper moving frame 36 and the upper moving base is used to realize the horizontal universal movement of the threaded mounting post 31. The second springs 38 arranged in a cross shape are used to reset the threaded mounting post 31 after it separates from the hole position deviation mother row through hole.

[0061] The lower mounting base 42 has a lower moving frame 45 slidably connected inside, and the lower moving frame 45 has a lower moving block 46 slidably connected inside, which is threadedly connected to the threaded mounting tube 41. The threaded connection between the threaded mounting tube 41 and the lower moving block 46 is used to realize the replacement of the corresponding cutter. A limit hole is opened on one side of the outer wall of the threaded mounting tube 41. The bottom of the lower moving block 46 is fixedly connected to an ear plate, and a limit screw that is threaded on the ear plate and inserted into the corresponding limit hole is used to realize the anti-deviation limit after the threaded mounting tube 41 is connected.

[0062] Both the lower mounting base 42 and the lower moving frame 45 are rotatably connected to screws 47, and a second servo motor 48 is fixedly installed to drive the corresponding screws 47 to rotate. The lower moving frame 45 and the lower mounting base 42 are threadedly connected to the corresponding screws 47. The corresponding screws 47 are controlled to rotate forward or backward by the corresponding second servo motor 48, which pushes the lower moving frame 45 or the lower moving block 46 to move, so as to realize the self-driven compensation hole position deviation of the threaded mounting tube 41 for cutting burr removal.

[0063] A photoelectric sensor transmitter is mounted on the U-shaped block 43, and a photoelectric sensor receiver is mounted on the bottom of the tapered guide post 33. A control panel 19 is mounted on the fixed base plate 1. The control panel 19 is electrically connected to the transmitter and receiver. During the position correction of the threaded mounting post 31, the receiver of the photoelectric sensor collects the signal of the beam emitted by the transmitter of the photoelectric sensor. When the threaded mounting post 31 moves to correct the hole position, the receiver receives the beam offset emitted by the transmitter. The controller generates an alignment signal and controls the corresponding second servo motor 48 to drive the corresponding screw 47 to rotate forward or reverse, pushing the lower moving frame 45 or the lower moving block 46 to move, causing the threaded mounting tube 41 to move synchronously with the threaded mounting post 31.

[0064] Example 3: Please refer to Figures 1-12 As shown, the present invention also proposes a method for using an automatic alignment processing device for finishing burrs on busbar through holes, comprising the following steps:

[0065] Step 1: The busbar is placed between two sets of V-shaped clamps 24 in one side positioning cavity, with one side abutting against the corresponding limiting plate 23. Then, the corresponding electric push rod 26 pushes the V-shaped clamps 24 to move relative to each other. Combined with the V-shaped groove of the V-shaped clamps 24, the busbars of different thicknesses are subjected to adaptive positioning and clamping treatment with vertical centering. The rotating wheel drives the bidirectional lead screw 25 to rotate, and the positions of the two sets of limiting plates 23 in the positioning cavity are adjusted synchronously, thereby further positioning the hole position of the busbar through hole. The electric cylinder slide table 21 pushes the fixing frame 22 to move, causing the fixed busbar to move between the upper frame 11 and the lower frame 12, and the burrs in the busbar through hole are squeezed and cut. The busbar is fixed synchronously through the other side positioning cavity.

[0066] Step 2: The first servo motor 14 drives the gear 15 to rotate. Combined with the meshing of the two sets of gear plates 16 and the gear 15, the upper frame 11 and the lower frame 12 move synchronously relative to each other. The upper frame 11 adopts rigid descent, and the lower frame 12 adopts elastic ascent. The tapered guide post 33 at the bottom of the threaded mounting post 31 first contacts the busbar through hole. If there is a centerline deviation between the busbar through hole and the tapered guide post 33, the position of the threaded mounting post 31 is automatically corrected through the inclined surface at the bottom of the tapered guide post 33 and the sliding installation of the upper moving frame 36 and the upper moving seat, so that the axis of the threaded mounting post 31 coincides with the centerline of the corresponding busbar through hole.

[0067] Step 3: During the position correction of the threaded mounting post 31, the receiver of the photoelectric sensor collects the signal of the beam emitted by the transmitter of the photoelectric sensor and transmits the collected signal to the controller in the control panel 19. When the receiver receives the beam emitted by the transmitter, the controller generates a position signal without any processing.

[0068] When the threaded mounting post 31 moves to correct the hole position, the receiver receives the beam deflection emitted by the transmitter, the controller generates an alignment signal and controls the corresponding second servo motor 48 to drive the corresponding screw 47 to rotate forward or reverse, pushing the lower moving frame 45 or the lower moving block 46 to move, causing the threaded mounting tube 41 to move synchronously with the threaded mounting post 31.

[0069] Step 4: After the positions of the threaded mounting post 31 and the threaded mounting tube 41 are corrected, they enter the through hole of the busbar through the relative movement of the upper frame 11 and the lower frame 12. First, the saw cutter 34 on the threaded mounting post 31 and the threaded mounting tube 41 cuts the large burrs inside the through hole. Then, the flat cutter 35 quickly trims the inner wall surface of the busbar through hole. The cut burrs enter the threaded mounting tube 41 and then enter the chip cylinder 44 for collection. With the help of the relative movement of the threaded mounting post 31 and the threaded mounting tube 41, the burrs in the busbar through hole are subjected to deep and rapid cutting and extrusion cutting.

[0070] Step 5: The threaded mounting post 31 continues to move downwards, and after the tapered guide post 33 comes into contact with the U-shaped block 43, the rigidity of the upper frame 11 decreases and the elasticity of the lower frame 12 increases, pushing the threaded mounting tube 41 to move downwards relative to each other, compressing the first spring 17. The saw cutter 34 and the flat cutter 35 on the threaded mounting post 31 are used to fully trim the inner wall of the through hole between the threaded mounting post 31 and the threaded mounting tube 41.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
